Abstract
The utility model discloses a kind of petroleum casing pipe, comprise pin end and box end, it is characterized in that, described pin end comprises sheath cylindrical shell, sheath handle, strengthening groove and rubber inner sleeve, described sheath handle is located at above described pin end, and described sheath cylindrical shell and described rubber inner sleeve are equipped with.A kind of petroleum casing pipe that the utility model provides, pin end eliminates steel tube dirt-proof boot and polybag, also simplify installation and removal operation, and can stop oil specialized barrel completely when by outer wall of steel pipe impeller blasting equipment, steel sand enters screw thread; The combination of box end and pin end is similar to the drop bottle closure of rubber of glass, effectively blocks the gap of thread protector and body quality inspection, not yielding, can block box very regularly, stop steel sand completely and enter box.
Description
Technical field
The utility model relates to a kind of petroleum casing pipe.
Background technology
Petroleum casing pipe general in prior art is divided into pin end and box end, pin end of the prior art generally adopts rubber sheath, steel tube dirt-proof boot, " O " type rubber seal and polybag to carry out the protection of steel sand, exist operation sequence loaded down with trivial details, effectively can not stop the problem that steel sand enters sleeve pipe screw thread, and box end generally adopts rubber plug, go deep into body, prevent steel sand from entering body, but the gap can not blocked between thread protector and body, exist rubber plug yielding, not just, the problem such as lax, steel sand may be caused to enter.
Therefore, prior art needs to be improved.
